Abstract

A potassium hexatitanate whisker having a tunnel structure containing aluminum and niobium impurities in such amounts that Al 2 O 3 /Nb 2 O 5 molar ratio is 0.6 or higher and composite materials using the same. Also disclosed are processes for producing composite materials using the potassium hexatitanate whiskers having a tunnel structure with a light alloy or a thermoplastic resin.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
       1. A potassium hexatitanate whisker having a tunnel structure containing aluminum and niobium impurities in such amounts that the Al 2  O 3  /Nb 2  O 5  molar ratio is at least 0.6 and containing 1% or less by weight in total of impurities as oxides other than aluminum and niobium. 
     
     
       2. An alloy-base composite material comprising a light alloy matrix and potassium hexatitanate whiskers having a tunnel structure, said whiskers containing aluminum and niobium impurities in such amounts that the Al 2  O 3  /Nb 2  O 5  molar ratio is at least 0.6 and containing 1% or less by weight in total of the whiskers impurities as oxides other than aluminum and niobium.
